use of liquid chlorine in AG vinyl lined pool

[Darkside]

i had a CYA of 70-80 a few days ago, but today i dont even reach 100 before the black dot goes away. i didnt add all 4 jugs of bleach last night, just 1 jug. i will try the dilution test tomorrow after work. my pool doesnt have a strong chlorine odor at this time, actually very little chlorine odor. i will order the K-1515 tonight. my filter doesnt use sand its just a plain old cartridge filter. i was talking with my wife and the filter is actually two years old... oops. i never had a cloudy water problem before, so im going to order a new filter tonight just to rule that out. ill keep my current filter as a back up.

thanks for the help!

Then, your CYA is over 100. Try the dilution test on this one, too, to try and see if you can't get a little closer reading. Dilution isn't super accurate, but better than nothing.
Why is your CYA climbing? Have you added some recently and if so, when and how much? Or are you using a stabilized form of chlorine such as trichlor tabs or dichlor shock powder?

Glad to hear you didn't add all that chlorine at once!

i was able to do the chlorine dilution test and the color was a very light pink color. i used 1 part tap water and 1 part pool water and 5 drops each of R-001 and R-002.

i was using both trichlor tabs and dichlor shock but have stopped using them. i will try the dillution CYA test and post back. i will need to get more R-0013 since i only have one bottle left.

i just ordered the K-1515 and a new filter, thanks again for the help!

I'm concerned that you have no chlorine in your pool and you're in another algae fight. I'm sorry to disagree with you watermom.

If you read this before leaving work, please pick up a cheap OTO/pH test kit on your way home. It wil definitively tell you if you have lots or no chlorine; OTO doesn't bleach out. If your wall mart has the HTH 6-way kit (check availability), get that, it will supplement your K-2006 and give you an OTO kit as well.

If you have no FC, you need to get to shock level (25ppm+) and keep it there until you have less tham 1ppm loss of FC overnight and 0.5ppm or less CC.
Two big jugs (1.42gal) of 6% bleach should get you near 25ppm.

When I advised not to add any more bleach at that point it was because I thought all 4 big jugs of bleach had been added at once. If that had been the case, the DPD test would have been bleached out and thus reading 0 chlorine. After I wrote that, the OP clarified in a later post that all the jugs were not added all at once.

i added approx 2 lbs of borax this monring before work since it was low ( below 7.0 ) tested after work and PH is was 7.2 so i added the rest of the box or borax approx 2 more pounds and retested an hour later PH is now 7.6

FC is still 0. i also did a diluted CYA test by mixing 1 part tap water and 1 part pool water for the test. i put 7ml in the small bottle and then added 7ml of R-0013, mixed for 30 seconds and got a reading of 70 at the time the black dot disapeared. so this tells me i have high CYA right?

i just added 2 big jugs 2.84 gal total to the pool. i also noticed big brownish/green splothces on the pool floor so the battle goes on! water is still cloudy.

i will test FC after dinner if it doesnt start to down pour, and ill be heading to walmart later for more chlorine and borax. i know my local walmart doesnt have the kit bigdave mentioned at this time as i looked for it before picking up the K-2005 i just bought.

the good news is my K-1515 and filter shipped today! am i basically making my K-2005 a K-2006 by adding the K-1515?

[BigDave]

WM; you are (of course) absolutely right. I just noticed that Darkside had a legitimate FC of 0 and hadn't added any chlorine since. I hope I haven't offended you.

[Watermom]

With the addition of the K-1515, you will basically have the K-2006.

If you got a CYA reading of 70 with a 50:50 dilution, then that means your reading is actually 140. You will have to shock to 25 while you are fighting to clear your water and then once it is all cleared up, you'll have to be diligent about keeping your chlorine between 8-15 ALL the time or you'll be right back where you started!

Your pH is good at 7.6.

Run your pump 24/7 and clean the filter as needed. Hang in there!

EDIT to add ---- Can you please make a signature line which gives the type of pool, volume, type of filter, size of pump, any other equipment you have and also the type of test kits. That makes it easier for us to help instead of having to continually scroll back up looking for details about your pool. See the link in my signature for how to do so.

just tested and FC is too high for my test to read, so i should measure again in the morning right? also PH is now 8.0
